She's a buxom blonde who doesn't have that bimbo quality to her. She usually goes by "Avalon" but often by "Jennifer" or "Jennifer Avalon" nad in a couple of cases, "Michelle".

Does she provide?

She also did some work for Playboy as "Tracy Ryan"

I'm not sure what the "bimbo quality" is or whether this blonde hottie fits within that category, but I leave that to the individual.
She's been, Jennifer Avalon, Avalon, Tracy Smith, Wendy and a couple other names that escape me 'cause they're so damn numerous. I think I recall her in Playboy, Perfect 10, a model for ALSSCAN.COM (Wendy), I recall a couple of scenes in the Pick-up Lines series of videos, and a video called Liquid Gold #? where she pees in to a pitcher and then supposedly drinks it after. She does other things too, but obviously the key act here is urine specific.
Honestly, a gorgeous specimen for sure, but, as I said, I don't know what the qualifications for bimbohood are.
